AND D IAGNOSTIC P ROCEDURES
Urden: Priorities in Critical Care Nursing, 8th Edition
MULTIPLE CHOICE
1. A patient was admitted with acute kidney injury. Which urinalysis value
reflects a decreased abilit y of the kidneys to concentrate urine?
a. pH of 5.0
b. Specific gravit y of 1.000
c. No casts
d. Urine sodium of 1 40 mEq/24 hr
ANS: B
Specific gravit y measures the densit y or weight of urine compared with
that of distilled water. The normal urinary specific gravit y is 1.005 to
1.025. For comparison, the specific gravity of distilled water is 1.000.
Because urine is composed of many solutes and substances suspended
in water, the specific gravit y should always be higher than that of
water.

, 2. A patient is admitted in acute kidney injury. The patient reports that
over the past few weeks, his urine output has decreased, and he has
developed peripheral edema and ascites . The nurse suspects the main
cause of ascites is what condition?
a. Hypervolemia
b. Dehydration
c. Volume overload
d. Liver damage
ANS: C
Individuals with acute kidney injury may have ascites caused by
volume overload, which forces fluid into the abdomen because o f
increased capillary hydrostatic pressures. However, ascites may or may
not represent fluid volume excess.

3. A patient is admitted in acute heart failure secondary to renal
insufficiency. The patient reports that over the past few weeks, his urine
output has decreased, and he has developed peripheral edema and
ascites. Which diagnostic tests would provide the best information about
the internal kidney structures, such as the parenchyma, cal yces, pelvis,
ureters, and bladder?
a. Kidney–ureter–bladder (KUB)
b. Intravenous pyelography (IVP)
c. Renal ultrasonography (ECH O)
d. Renal angiography
